If you've been on a Southwest flight, you've no doubt heard the Flight Attendant ask for change for a $20 bill. Well, those days are going the way of knee socks and penny loafers (did I just date myself?). Beginning September 9, Southwest will "flip the switch" and accept only credit and debit cards for beer, liquor, and energy drink purchases.

As a kid, I hated the summer Olympics. We had five television channels, and every single one of them showed the Olympics for three weeks straight. No Smurfs. No Looney Tunes. No Mr. Roger's Neighborhood. Just a bunch of boring adults doing boring things like running and swimming. I did those things every day and didn't understand why it was such a big deal to watch other people doing it.
